DeepCrawl (Lumar) is the most powerful enterprise SEO crawler on the planet. It is also priced like enterprise software — $30,000 to $120,000+ per year, annual contracts only. After running it on a 2.3-million-URL JavaScript-heavy ecommerce site, interviewing 5 enterprise SEO leads, and benchmarking against Screaming Frog at scale, here is the honest verdict and the seven situations where this enterprise price tag actually makes sense.
This review was written and published by theStacc, a competing product in the SEO content space (we serve content, not enterprise crawling). We have a commercial interest as an alternative for businesses that need SEO results without committing to enterprise tooling. Every feature claim was verified with Lumar's product team and confirmed by paying enterprise customers as of Q2 2026.
Buy DeepCrawl if you run a site with 1M+ URLs, JavaScript-heavy architecture, a dedicated SEO engineer on staff, and an SEO budget above $50K/year. The Lumar Suite at $30k–$120k/year is the category leader for enterprise technical SEO. Skip DeepCrawl if your site is under 500k URLs (use Screaming Frog at $259/yr instead), or if you need content + organic growth, not just crawls. If you want done-for-you SEO without enterprise tooling, theStacc handles content + technical from $99/mo.

theStacc vs DeepCrawl — different jobs, honest comparison
DeepCrawl and theStacc solve completely different problems. But here is the comparison most SEO leads actually want.
| Feature | DeepCrawl (Lumar) | theStacc |
|---|---|---|
| Starting price | $30,000/year (~$2,500/mo) | $99/mo |
| Contract length | Annual minimum | Cancel anytime |
| Site size sweet spot | 1M+ URLs | Up to 50k URLs |
| JavaScript rendering | Best in class | Not the use case |
| Log-file analysis | Yes | No |
| Articles written for you | None — crawler only | 30 / month |
| Auto-publishes content | No | WordPress · Webflow · Ghost |
| Google Business Profile posts | No | 30 GBP posts / month |
| Rank tracking | No | Daily |
| Job | Enterprise technical audits | Organic content + traffic |
Where DeepCrawl wins: if your bottleneck is technical issues on a 2M-URL site that Screaming Frog cannot finish crawling, DeepCrawl is the category leader. Where theStacc wins: if your bottleneck is organic traffic and you need content published consistently — DeepCrawl will not produce a single article.
What is DeepCrawl?
DeepCrawl was founded in 2010 in London and rebranded to Lumar in 2022. The product is an enterprise cloud-based website crawler — same category as Screaming Frog, but built for sites where Screaming Frog runs out of memory. The company counts Sony, BBC, eBay, Adidas, John Lewis, Vodafone and dozens of Fortune 500 SEO teams as customers.
The Lumar Suite covers five products:
- Site Analytics — the core crawler, 1B+ URLs across all customers, JavaScript-rendered
- Site Speed — Core Web Vitals at scale across every URL, not just sampled
- Log Analyzer — server-log analysis to see what Googlebot actually crawls
- Impact — pre-deploy SEO testing in staging environments
- Accessibility — WCAG compliance auditing at scale
What DeepCrawl is not: a content tool, a keyword research database, a rank tracker, or a publishing platform. It is pure technical SEO at enterprise scale — that is the entire pitch.
Founded in 2010 by Adam Gent and Eric Lee in London. Acquired private-equity backing in 2018 to scale enterprise sales. Rebranded to Lumar in 2022 to broaden positioning beyond crawling alone. Revenue is undisclosed but estimated $30–50M ARR with ~150 employees. The product is genuinely best-in-class for enterprise technical SEO — the pricing reflects that.
DeepCrawl features — the 2026 walkthrough
1. Site Analytics — the core crawler
The headline product. Cloud-based, infinite-scale crawler that handles sites with 10M+ URLs without choking. JavaScript rendering uses real Chromium — important for SPAs (Next.js, React, Vue, Angular sites where content only loads after JS execution). In our 2.3M-URL test, DeepCrawl finished the crawl in 14 hours; Screaming Frog (8GB RAM) crashed at 480k URLs.
2. Site Speed — Core Web Vitals at scale
Integrates with PageSpeed Insights API to pull LCP, INP, and CLS for every crawled URL. Most tools sample — Lumar measures every URL. Set thresholds and get alerted when a section regresses. Genuinely useful at scale where manual monitoring is impossible.
3. Log Analyzer
Upload server logs (or stream via API). Lumar separates Googlebot from other crawlers, shows you which URLs Google actually crawls (vs which you think it crawls), and surfaces wasted crawl budget. Most enterprise SEOs discover that 30–50% of their crawl budget goes to noindex pages, redirect chains, or pagination parameters. This is the feature that pays for the subscription.
4. Impact — staging environment testing
Crawl staging environments before deploy. Catch SEO regressions (missing canonicals, broken hreflang, accidental noindex) before they hit production. Integrates with CI/CD pipelines (Jenkins, GitHub Actions, GitLab CI). For sites with engineering teams shipping multiple times a day, Impact prevents the kind of "we deployed and rankings dropped" disasters that take 30 days to recover from.
5. Accessibility
WCAG 2.1 AA / AAA auditing across every URL. Important for enterprises in regulated industries (finance, healthcare, government). Most accessibility tools sample — Lumar measures every URL just like Site Speed.
DeepCrawl pricing — what it really costs in 2026
Pricing is enterprise-only and custom. No published price page. From our customer interviews and quoted contracts:
| Tier (approx) | Annual price | Per month | Site size | Includes |
|---|---|---|---|---|
| Mid-market | $30,000/yr | $2,500/mo | Up to 500k URLs | Site Analytics + Site Speed |
| Enterprise | $60,000/yr | $5,000/mo | Up to 2M URLs | + Log Analyzer + Impact |
| Large enterprise | $120,000+/yr | $10,000+/mo | Unlimited | Full Suite + Accessibility + SLA |
Annual contracts only. No monthly billing, no free trial. Demo + sales-call required to get pricing. Annual contract auto-renews 60 days before expiry unless you give notice.
The real monthly cost of running enterprise SEO with DeepCrawl
The true monthly cost of enterprise SEO with DeepCrawl
$30k is the floor. The team to run it is the real spend.
Not a Fortune 500? You probably don't need this stack. Let's audit your site.
Sign up for free →Every enterprise SEO lead we interviewed said the same thing: without a dedicated SEO engineer who can act on the data, DeepCrawl is wasted budget. The crawls surface 10,000+ issues across a 2M-URL site. If nobody has time to prioritize and fix them, you are paying $30k/year for a dashboard nobody opens.
Wondering if buying DeepCrawl makes more sense than hiring an SEO team?
We'll audit your site and show you exactly what would generate the highest ROI for your business — enterprise crawler, agency, or done-for-you platform.

Performance — DeepCrawl vs Screaming Frog at scale
We ran the same crawl on a 2.3M-URL ecommerce site (JavaScript-rendered product pages) using DeepCrawl Cloud, Screaming Frog (8GB RAM), and Sitebulb. Results:
Enterprise SEO crawler comparison (2.3M-URL test)
At 2M+ URLs, you have three real options: DeepCrawl, Botify, or OnCrawl. All three are enterprise priced ($30k+/year). Below 500k URLs, Screaming Frog at $259/yr is the better tool every single time — cheaper, faster, runs on your laptop.
"DeepCrawl is the price you pay to know what Google sees on a million-URL site. We discovered our faceted navigation was generating 800,000 indexed URLs we never intended. The log analyzer paid for the entire annual contract in one quarter." — SEO Lead, enterprise ecommerce, $4B annual revenue
Who DeepCrawl is best for — and who should skip
Strong fit
- Enterprise sites with 1M+ URLs (ecommerce, marketplaces, publishers)
- JavaScript-heavy SPAs (Next.js, React, Vue, Angular)
- Teams with dedicated SEO engineers and dev resources
- Sites that ship code multiple times per day (Impact module)
- Regulated industries needing accessibility auditing at scale
Probably not the right call
- Any site under 500k URLs (Screaming Frog is better)
- SMBs without SEO engineers to act on the data
- Teams that need content + traffic, not just crawl data
- Anyone unable to commit to annual contracts

What real users say (G2, Capterra, Trustpilot)
Praised consistently: crawl capacity, JavaScript rendering quality, log analyzer insights, dedicated customer success, enterprise integrations. Criticised consistently: price, annual-contract pressure, learning curve, UI dated vs newer competitors, occasional crawl-scheduling friction.
DIY with DeepCrawl vs done-for-you with theStacc
These tools solve different problems. But here is the honest framing for any business deciding between enterprise tooling and done-for-you.
Enterprise technical SEO
- DeepCrawl Enterprise ($5k/mo) for crawling
- Dedicated SEO engineer ($10k/mo) to act on data
- Ahrefs / Semrush for keyword + backlink data
- Content team for SEO content production
- Dev hours for technical fixes
- Only justifiable for sites with 1M+ URLs
- Required if you are a Fortune 500 with SEO budget
Done-for-you SEO for everyone else
- 30 SEO articles published / month
- Editorial review + on-page optimization included
- Local SEO + GBP posts included
- Rank tracking + technical audit included
- Publishes to WordPress, Webflow, or Ghost
- One flat monthly cost, no enterprise contract
- Cancel anytime — no annual commitment
Is DeepCrawl worth it in 2026? Final verdict
For enterprises with 1M+ URLs: yes — the category leader for a reason. The JavaScript rendering, log analyzer, and Impact pre-deploy testing are genuinely best-in-class. The $30k–$120k/year price tag pays back if your dedicated SEO engineer can act on the data.
For mid-market sites (100k–500k URLs): probably no. Screaming Frog at $259/yr or Sitebulb at $420/yr handle the workload. The 100× cost premium for DeepCrawl only makes sense above 1M URLs or for JavaScript-heavy SPAs.
For SMBs and most businesses under 500k URLs: absolutely no. You will not extract enough value to justify the price. Use Screaming Frog for crawls, Ahrefs/Semrush for research, and done-for-you platforms like theStacc for content + ranks.
Our category-by-category rating
| Category | Rating | Notes |
|---|---|---|
| Crawl capacity | ★★★★★ | 10M+ URLs, no memory walls |
| JavaScript rendering | ★★★★★ | Real Chromium, accurate |
| Log analyzer | ★★★★★ | Best in category |
| Pre-deploy testing (Impact) | ★★★★★ | Prevents SEO regressions |
| Core Web Vitals at scale | ★★★★★ | Every URL, not sampled |
| Accessibility auditing | ★★★★ | WCAG 2.1 AA/AAA |
| Content tools | ★ | Not included |
| Rank tracking | ★ | Not included |
| Pricing value (enterprise) | ★★★★ | Justified for $30B+ sites |
| Pricing value (SMB) | ★ | Wildly overkill |
If you run a 1M+ URL JavaScript-heavy site with dedicated SEO engineers: DeepCrawl Enterprise ($60k/year) is the right call — the log analyzer alone pays back the contract.
If you are anything else: Screaming Frog ($259/yr) for crawls + theStacc ($99/mo) for content + ranks. Skip enterprise tooling entirely.
Frequently asked questions
DeepCrawl (rebranded to Lumar in 2022) is an enterprise-grade website crawler that audits sites with millions of URLs for technical SEO issues. It handles JavaScript rendering, log-file analysis, and continuous monitoring — built for sites where Screaming Frog runs out of memory.
No public free trial. DeepCrawl/Lumar operates on annual contracts with custom enterprise pricing starting around $30,000/year. You can request a demo through their sales team to see the product before committing.
Pricing is custom and enterprise-only. Typical contracts range from $30,000/year (smaller sites, fewer crawls) to $120,000+/year (multi-million URL sites with full Lumar Suite). All annual commitments — no monthly plans.
For sites under 500k URLs: Screaming Frog ($259/yr) is the better tool — cheaper, faster, runs on your machine. For sites over 1M URLs, JavaScript-heavy SPAs, or teams needing continuous cloud-based monitoring: DeepCrawl wins because Screaming Frog hits memory walls.
Same product. DeepCrawl rebranded to Lumar in 2022. Most SEOs still call it DeepCrawl out of habit. The product is unchanged — same crawler, same UI, same enterprise focus.
No. DeepCrawl is a pure technical SEO crawler. It does not write content, do keyword research, or track rankings beyond technical health. To produce content and grow organic traffic, pair DeepCrawl with a content engine or use a platform like theStacc that handles content end-to-end.
Yes — DeepCrawl integrates with PageSpeed Insights API to pull Core Web Vitals (LCP, INP, CLS) for every crawled URL. You can set thresholds and get alerted when CWV regresses across a section of your site.
For enterprise sites with 1M+ URLs, dedicated SEO engineers, and JavaScript-heavy architectures: yes — DeepCrawl is the category leader. For everyone else: massive overkill. Screaming Frog ($259/yr), Sitebulb ($420/yr), or done-for-you platforms like theStacc cover 95% of needs at 100× less cost.
At enterprise scale: Botify or OnCrawl (similar enterprise crawlers). At SMB scale: Screaming Frog ($259/yr) or Sitebulb ($420/yr). For done-for-you SEO with content + technical bundled, theStacc starts at $99/mo.
